2014-09-13Add KLEE specific DEBUG macros.Daniel Dunbar
- This allows us to build in +Asserts mode even when LLVM isn't (by disabling the checks in that mode). - Eventually it would be nice to just move off of LLVM's DEBUG infrastructure entirely and just have our own copy, but this works for now. - Fixes #150.
2014-09-12[FloatEvaluation] Use llvm::report_fatal_error() instead of assert(0) for ↵Daniel Dunbar
unsupported floating point widths.
2014-09-12When building against libc++ (vs libstdcxx), use standard ↵Daniel Dunbar
unordered_{map,set} includes. - I'm not sure what the status of libstdcxx's c++11 support is. It may be we can just move over to <unordered_map> everywhere, but I don't have a Linux test machine handy at the moment.

2014-09-12Regenerate configure with sanctioned autoconf version.Daniel Dunbar
2014-05-30Fix ExprTest under LLVM 2.9Martin Nowack
2014-05-29Remove #include <iostream> to avoid static constructorsMartin Nowack
iostream injects static constructor function into every compilation unit. Remove this to avoid it.
2014-05-29Refactoring from std::ostream to llvm::raw_ostreamMartin Nowack
According to LLVM: lightweight and simpler implementation of streams.
2014-04-24Merge pull request #116 from MartinNowack/fix_mallocDan Liew
Fix handling of memory usage in KLEE.

klee::util::GetTotalMemoryUsage()
2014-04-24Fix handling of memory usage in KLEE.Martin Nowack
Memory usage API in LLVM since 3.3 is not working the way it is intended by KLEE. This ports the pre 3.3. version to KLEE. Fixes the malloc test case.
2014-04-24Add missing newline at end of file to silence a clang warning.Dan Liew
2014-04-24Asserting that update lists have non-NULL roots within ReadExpr objects (updateHristina Palikareva
lists can have NULL roots, e.g. in MemoryObject instances with concrete contents, where root is allocated lazily only when the updates are required). Also checking whether array updates are typed correctly in UpdateList::extend() rather than in the constructor of UpdateNode (only for update lists with non-NULL roots).
2014-04-16Removing a few more hard-coded values for domains and ranges of Array objectsHristina Palikareva
2014-04-15Associate a domain and range with each arrayPeter Collingbourne
2014-04-04Add the ability to control whether the pretty printer uses line breaksPeter Collingbourne
This change makes it possible to more reliably write unit tests which check that an expression is equivalent to an expected pretty printed string.

2014-01-12Merge pull request #68 from MartinNowack/feature_kleeInternalFunctionsDan Liew
Feature klee internal functions
2013-12-21klee-uclibc detection is now a lot cleaner. KLEE now assumesDan Liew
it can find klee-uclibc inside the same folder as the other runtime libraries with the name "klee-uclibc.bca" This is implemented as follows: * When building, a sym-link is created to klee-uclibc's libc.a file in the same directory that the rest of KLEE's runtime libraries are built. This done so that if a developer changes klee-uclibc on their system then the correct version of klee-uclibc is used by KLEE. * When installing, klee-uclibc's libc.a file is installed in the same directory that the rest of KLEE's runtime libraries are installed. In addition the configure script argument --with-uclibc can now operate in two ways. It can either be passed the path to the root of klee-uclibc or it can be passed a path to the libc.a file built by klee-uclibc. This new behaviour has been added to allow users to potential use pre-built versions of klee-uclibc.
2013-12-19Allow to specify KLEE-internal functionsMartin Nowack
KLEE provides runtime library functions to do detection of bugs (e.g. overflow). This runtime functions are not the location of the bugs but it is the next non-runtime library function from the stack. Use the caller inside that function to indicate where the bug is.
2013-12-12Patch by Daniel Lupei, fixing a performance bug with theCristian Cadar
counterexample cache. (This is an old patch, reported at http://llvm.org/bugs/show_bug.cgi?id=11435, on KLEE's old bug tracking system.)

2013-09-21Merge pull request #17 from MartinNowack/LLVM33Cristian Cadar
Make KLEE compile with LLVM 2.3.
2013-09-02Implemented runtime check for overshift (controllable with --check-overshiftDan Liew
command line argument). Overshift is where a Shl, AShr or LShr has a shift width greater than the bit width of the first operand. This is undefined behaviour in LLVM so we report this as an error.
2013-08-28Fix constness warnings issued by gcc 4.7Martin Nowack
2013-08-28Silence compiler warning about unused variableMartin Nowack
2013-08-27Port to LLVM 3.3Martin Nowack
Major changes are: - Switching to llvm-link to build archive files - Use GetMallocUsage instead of GetTotalMemoryUsage (be aware of bug in LLVM 3.3 http://llvm.org/bugs/show_bug.cgi?id=16847) - intrinsic library functions like memcpy/mov/set use weak linkage to be replaced by e.g. uclibc functions - rewrote linking with library - enhanced MemoryLimit test case to check if mallocs were successful
2013-08-06TimingSolver and constructSolverChain() no longer coupled with pointers to ↵Hristina Palikareva
STPSolver objects. Timeout is now set by the solver at the top of the solver chain rather than by STPSolver.
2013-08-06Methods getConstraintLog() and setTimeout() made virtual and moved from ↵Hristina Palikareva
STPSolver to base Solver and SolverImpl classes, and consequently redefined in derived classes to call the corresponding methods down the solver chain. Method setTimeout() renamed to setCoreSolverTimeout().
2013-08-06Renaming solver-related command-line options in order to decouple them from ↵Hristina Palikareva
STP. More specifically, command-line options max-stp-time, use-forked-stp and stp-optimize-divides renamed to max-solver-time, use-forked-solver and solver-optimize-divides, respectively. Option of running the SMT solver in a separate process (i.e. forked) set to true by default. Options of running SMT solver forked and with optimized divides made available to Kleaver as well.
